[0021] 2. Specific examples of embodiments DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the configuration of a door and a cover fixing member for the door according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0022] Fig. 1 is a cross-sectional view of a door 1 equipped with a cover fixing member 4 according to an embodiment of the present invention. Fig. 2 is an exploded perspective view of the door 1 according to an embodiment of the present invention. In the following description, the surface on the near side of the paper in Fig. 2 is the front of the door 1. Fig. 3 is a partially enlarged exploded perspective view of the door 1 according to an embodiment of the present invention.

[0023] In the following description, the upper side refers to the upward direction (arrow c direction) when viewing the door 1 shown in Fig. 2 from the front, and the lower side refers to the downward direction (arrow d direction) when viewing the door 1 from the front. Therefore, the vertical direction, height direction, or gravity direction is referred to as the direction of arrow cd.

[0024] 2 is viewed from the front (arrow e direction), and the right side is viewed from the front (arrow f direction) of the door 1. Therefore, the left-right direction or horizontal direction is the direction of arrow ef.

[0025] Furthermore, the thickness direction of the door 1 shown in Fig. 2, i.e., the direction perpendicular to both the up-down direction and the left-right direction when the door 1 is viewed from the front and parallel to the short side direction of the side surface portion 21, is defined as the front-to-rear direction. Therefore, the thickness direction or the front-to-rear direction is defined as the direction of arrow ab. However, the above-mentioned front-to-rear direction, up-down direction, left-to-right direction, etc. are used for convenience of explanation, and can be defined as different directions depending on the usage situation in which the door 1 is placed.

[0026] As shown in FIG. 2, the door 1 is a sliding door that can move left and right along rails or grooves (neither of which are shown) provided in an opening (not shown). The door 1 includes a frame portion 2, a cover member 3 that covers a side portion 21 of the frame portion 2, and a cover fixing member 4 that is provided between the side portion 21 and the cover member 3. In this embodiment, the frame portion 2 of the door 1 is made of a metal such as an aluminum alloy. Also, in this embodiment, the cover member 3 is an extruded metal such as an aluminum alloy. Furthermore, in this embodiment, the cover fixing member 4 is made of a material that elastically deforms with a smaller force than the materials used for the frame portion 2 and the cover member 3, i.e., that is more easily deformed and restored from a molded shape than the materials used for the frame portion 2 and the cover member 3. Specifically, the cover fixing member 4 is, for example, a member molded using a resin material using a mold.

[0027] As shown in FIG. 2, the door 1 is a sliding door that can move left and right along rails and grooves (neither of which are shown) provided in an opening (not shown). The door 1 includes a frame portion 2, a cover member 3 that covers a side surface portion 21 of the frame portion 2, and a cover fixing member 4 that is provided between the side surface portion 21 and the cover member 3. The frame portion 2 is also provided with a groove portion 23 on the side surface in the short side direction that faces the above-mentioned rails and grooves. The surface of the frame portion 2 may be painted or covered with a decorative sheet or the like for design purposes.

[0028] FIG. 4 is a partially enlarged perspective view showing the side surface portion 21 of the frame portion 2 of the door 1 and the cover fixing member 4 in the embodiment of the present invention.

[0029] As shown in Figures 1 and 4, the recess 22 is formed in the side surface portion 21 of the door 1 as a groove extending in the vertical direction, which is the longitudinal direction. The recess 22 has a bottom portion 221 provided parallel to the side surface portion 21 and a side wall portion 222 extending perpendicularly from the bottom portion. Two recesses 22 are provided parallel to each other in the front-to-rear direction in the side surface portion 21. The side wall portion 222 is provided with a first elastic portion accommodating groove 223 for accommodating a first elastic portion 413, which will be described later, when the cover fixing member 4 is attached to the recess 22. A wall surface 224 is provided in the recess 22 on the inner side in the front-to-rear direction facing the side wall portion 222.

[0030] As shown in Figures 1, 2, and 3, the cover member 3 is a member that covers the side surface portion 21 from the outside, i.e., from the right side in Figure 2. The cover member 3 has a cover main body portion 31 and a protruding portion 32. In the cover member 3, the cover main body portion 31 is formed in a plate shape or a substantially plate shape with its longitudinal direction extending vertically in order to cover the portion of the side surface portion 21 where the groove-like recessed portion 22 extending vertically is formed. The cover main body portion 31 may be coated with paint or a decorative sheet having the same design as the frame portion 2 on the surface side exposed to the outside (the right side in Figure 2) when attached to the frame portion 2. The protruding portion 32 is a convex portion of the cover main body portion 31 that protrudes inward, i.e., toward the recessed portion 22 when attached to the side surface portion 21.

[0031] FIG. 5 is a partially enlarged cross-sectional view of the door 1 equipped with the cover fixing member 4 according to the embodiment of the present invention.

[0032] 5, the protrusion 32 has a protrusion main body 321 that protrudes toward the recess 22, and a claw 322 that protrudes from the protrusion main body 321 inward in the short direction of the side surface 21, i.e., inward in the front-to-rear direction (toward the a-b direction). By having the claw 322 protrude inward in the front-to-rear direction, it is possible to prevent the fitting of the cover member 3 into the recess 22 from being affected by factors such as the dimensional tolerances of the cover member 3 and the frame 2 and the thickness of a decorative member such as a sheet applied to the cover member 3. The protruding direction of the claw 322 is not limited to the above-mentioned direction, and it need only protrude in a direction that allows it to engage with an engaging portion 42, which will be described later.

[0033] Fig. 6 is a perspective view showing the cover fixing member 4 in the embodiment of the present invention. Fig. 7 is a cross-sectional view showing how the cover fixing member 4 and the cover member 3 are attached to the frame portion 2 of the door 1 in the embodiment of the present invention.

[0034] 1 to 7, the cover fixing member 4 has a base portion 41 that fits into the recess 22, and an engaging portion 42 that protrudes from the base portion 41 to the right in the left-right direction and engages with the protruding portion 32. The length of the cover fixing member 4 in the longitudinal direction may be shorter than the length of the recess 22 in the longitudinal direction.

[0035] The base portion 41 is formed in a rectangular or substantially rectangular shape in a plan view so that it can be press-fitted into the recess 22. The base portion 41 may be any type that allows the cover fixing member 4 to be fitted into the recess 22 and can be positioned so that the engaging portion 42 can engage with the protruding portion 32 of the cover member 3. The dimension of the base portion 41 in the front-to-rear direction (the ab direction) is desirably set so that there is a tolerance on the outside of the dimension of the recess 22 in the front-to-rear direction (the ab direction), that is, on the side away from the center of the recess 22. Specifically, the base portion 41 has, for example, a base portion 411, a first wall portion 412, a first elastic portion 413, a second wall portion 414, and a protruding portion 415.

[0036] The base portion 411 is a portion of the base portion 41 that faces the bottom portion 221 of the recessed portion 22. The base portion 411 is formed, for example, in a shape having a flat surface corresponding to the shape of the bottom portion 221 so that the base portion 41 can be attached to the recessed portion 22. The thickness of the base portion 411 in the horizontal direction (ef direction) is thinner in the central portion where the engagement portion 42 is provided than in both ends where the first wall portion 412 and the second wall portion 414 are provided. A protrusion 415 is provided on the base portion 411 (on the e side of the ef direction). The protrusion 415 is formed so as to be insertable into a hole 225 provided in the bottom portion 221 shown in FIG. 4.

[0037] The first wall portion 412 is a portion facing the side wall portion 222 of the recess 22. The first wall portion 412 is provided on the outer side in the front-to-rear direction (direction ab) corresponding to the side wall portion 222 so that the base portion 41 can be attached to the recess 22, and has a standing wall shape that rises in the left-to-right direction (direction ef). A first elastic portion 413 is provided at the tip of the first wall portion 412.

[0038] The first elastic portion 413 protrudes outward in the front-to-rear direction (direction ab) from the first wall portion 412 toward the side wall portion 222, and exerts elastic force on the side wall portion 222. The first elastic portion 413 is accommodated in a first elastic portion accommodating groove 223 provided in the side wall portion 222 when the cover fixing member 4 is attached to the recess 22. By being accommodated in the first elastic portion accommodating groove 223, the cover member 3 can be fixed to the frame portion 2 via the cover fixing member 4 more reliably.

[0039] The second wall portion 414 is provided as a standing wall on the side of the bottom portion 221 opposite to the side on which the first wall portion 412 is provided, i.e., on the inner end in the front-to-rear direction (direction ab). The second wall portion 414 is provided to face the wall surface 224. The height of the second wall portion 414 is higher than the first wall portion 412, and may be high enough to contact the cover main body portion 31 of the cover member 3 when the cover member 3 is attached, as shown in FIG. 6 , for example. By forming the second wall portion 414 in this manner, the cover fixing member 4 can increase the rigidity of the cover member 3 on the door 1.

[0040] In addition, by forming the second wall portion 414 as described above, the cover fixing member 4 prevents the cover member 3 from coming into direct contact with the frame portion 2, thereby preventing contact noise between the cover member 3 and the frame portion 2 caused by vibrations when the door 1 is opened or closed.

[0041] The engaging portion 42 has an engaging portion main body 421 and a second elastic portion 422. The engaging portion main body 421 protrudes from the base portion 41 toward the cover member 3, for example, to the right in the left-right direction (the f side in the ef direction). The second elastic portion 422 is provided at the tip of the engaging portion main body 421. The second elastic portion 422 has a shape that protrudes outward in the front-rear direction (the ab direction) so as to exert an elastic force on the claw portion 322.

[0042] <Action and effect> As shown in FIG. 7, in the door 1, the cover fixing member 4 made of a material that is more easily elastically deformed than the frame portion 2 and the cover member 3, for example, a resin, is attached by elastically pressing the base portion 41 into a recess 22 provided in the side portion 21 of the frame portion 2 made of an extruded material such as metal.

[0043] The cover fixing member 4 includes a base portion 41 and an engaging portion 42. The base portion 41 includes a base portion 411 that is generally rectangular in plan view, a first wall portion 412 provided at one end of the base portion 411 in the short direction, i.e., on the outer side in the front-to-rear direction, a first elastic portion 413 provided on the first wall portion 412 so as to protrude toward the side wall portion 222, and a second wall portion 414 provided at the other end opposite the first wall portion 412. The engaging portion 42 includes a second elastic portion 422 provided near the center of the base portion 411 and parallel to the first wall portion 412, the second wall portion 414, and the first elastic portion 413.

[0044] The cover fixing member 4 as described above is attached to the recess 22 of the frame portion 2 of the door 1. The cover fixing member 4 is made of resin, which is a material that is more elastically deformable than the frame portion 2 and the cover member 3, and therefore exerts an elastic force on the recess 22 to be fixed to the recess 22. Furthermore, the second wall portion 414 of the cover fixing member 4 abuts against the wall surface 224 of the recess 22, the first elastic portion 413 provided on the first wall portion 412 presses against the side wall portion 222 of the recess 22, and the tip of the first elastic portion 413 is accommodated in the first elastic portion accommodating groove 223 provided in the side wall portion 222.

[0045] In addition, the cover fixing member 4 has the second elastic portion 422 of the engaging portion 42 engaged with the protrusion 32 provided on the cover member 3, whereby the cover member 3 is fixed to the side surface portion 21 of the frame portion 2 of the door 1.

[0046] According to the above configuration, the door 1 is provided with the cover fixing member 4, and the cover member 3 is an elastic member that has the property of being more easily deformed than the frame member 2 and the cover member 3. This absorbs dimensional tolerances (variations) that occur in the frame member 2 and the cover member 3, which are made of extruded metal such as aluminum alloy, and dimensional differences due to the application of decorative materials such as sheets, and therefore the cover member 3 can be fixed to the frame member 2 without being affected by dimensional variations. Furthermore, according to the above configuration, because the cover fixing member 4 has the property of being more easily deformed than the frame member 2 and the cover member 3, the frame member 2 and the cover member 3 can be easily and reliably fixed together without using adhesives or other components that may affect the design, such as screws.

[0047] Furthermore, with the above configuration, the cover fixing member 4 has the property of being more easily deformed than the frame portion 2 and the cover member 3, so that the dimensional accuracy can be easily kept within a predetermined range.

[0048] In the cover fixing member 4, the base 411 is formed so that the thickness in the horizontal direction (ef direction) is thinner at the center where the engagement portion 42 is provided than at both ends where the first wall portion 412 and the second wall portion 414 are provided. By making the thickness of the center portion of the base 411 thinner than at both ends, when the base 411 is inserted into the recess 22 to fit the cover fixing member 4 into the recess 22, both ends slightly bend toward the center around the center of the base 411. This makes it easier for the cover fixing member 4 to fit into the recess 22, and after fitting, it exerts elastic force on the recess 22 to be securely fixed. In other words, the cover fixing member 4 can fit into the cover member 3 by exerting elastic force on it. By pushing the cover member 3, which is to be fixed together with the cover fixing member 4, into the recess 22, a force acts to expand the cover fixing member 4 in the front-to-rear direction (ab direction), allowing it to be more securely fixed to the frame portion 2.

[0049] Furthermore, according to the above configuration, in the door 1, the cover fixing member 4 can be fixed simply by pressing in, and has a property that makes it easier to deform than the frame portion 2 and the cover member 3, so the cover member 3 can be fixed to the frame portion 2 using elastic force, and since the cover member 3 can be easily attached and detached from the frame portion 2, maintenance can also be improved.

[0050] 3. Other embodiments Fig. 8 is a cross-sectional view of a three-sided frame 1B equipped with a cover fixing member according to another embodiment of the present invention. Fig. 9 is a partially enlarged cross-sectional view of a three-sided frame 1B equipped with a cover fixing member according to another embodiment of the present invention. Fig. 10 is a partial perspective view showing a side portion of a frame part of a three-sided frame 1B according to another embodiment of the present invention. Fig. 11 is a perspective view showing a cover fixing member according to another embodiment of the present invention.

[0051] As shown in Figures 8 to 11, in this embodiment, the frame portion 2B and cover member 3B of the three-sided jamb 1B are made of a metal, such as an aluminum alloy. Furthermore, in this embodiment, the cover fixing member 4B is formed of a material that elastically deforms with a smaller force than the material used for the frame portion 2B and cover member 3B. Unlike the cover fixing member 4 provided on the door 1 described above, the cover fixing member 4B is provided on the frame portion 2B of the three-sided jamb 1B. The three-sided jamb 1B includes a cover member 3B that covers a side surface portion 21B of the frame portion 2B, and a cover fixing member 4B provided between the side surface portion 21B and the cover member 3B.

[0052] In the frame portion 2B, the recess 22B is similar to the recess 22 described above in that it is formed in the shape of a groove extending in the longitudinal direction, that is, the up-down direction, on the side surface portion 21B, but differs in that only one recess 22B is provided on the side surface portion 21B.

[0053] Similar to the previously described cover member 3, the cover member 3B is a metal member that covers the outside of the side surface portion 21, i.e., from the right side in FIG. 2, and has a cover main body portion 31B and a protrusion portion 32B. In the cover member 3B, the cover main body portion 31B is formed in a plate or approximately plate shape with its longitudinal direction extending vertically in order to cover one groove-like recess 22B that extends vertically in the side surface portion 21B. Similar to the previously described protrusion portion 32, the protrusion portion 32B has a protrusion main body portion 321B and a claw portion 322B.

[0054] Similar to the cover fixing member 4 described above, the cover fixing member 4B has a base portion 41B that fits into the recessed portion 22B, and an engaging portion 42B that protrudes from the base portion 41B to the right in the left-right direction and engages with the protruding portion 32. The cover fixing member 4B differs from the cover fixing member 4 described above in that there is two engaging portions 42B per cover fixing member 4, corresponding to the fact that there is only one recessed portion 22B.

[0055] Like the base portion 41, the base portion 41B is formed in a rectangular or substantially rectangular shape in a plan view so as to be press-fitted into the recessed portion 22B. Specifically, the base portion 41B has, for example, a base portion 411B, a first wall portion 412B, a first elastic portion 413B, a second wall portion 414B, and a convex portion (not shown). Unlike the base portion 41, the base portion 41B has the first wall portion 412B at both ends of the base portion 411B in the front-to-rear direction (the ab direction). Furthermore, unlike the base portion 41, the second wall portion 414 of the base portion 41B does not contact the recessed portion 22B.

[0056] The first wall portion 412B is a portion facing the side wall portion 222B of the recess 22B. The first wall portion 412B is provided on both ends in the front-rear direction (the ab direction) corresponding to the side wall portion 222B so that the base portion 41B can be attached to the recess 22B, and has a standing wall shape that rises in the left-right direction (the ef direction). Similar to the first wall portion 412, the first wall portion 412B has a first elastic portion 413B provided at its tip.

[0057] The second wall portion 414B is provided as an upright wall on the center side of the bottom portion 221B. Similar to the second wall portion 414 described above, the height of the second wall portion 414B may be such that it comes into contact with the cover main body portion 31B of the cover member 3B when the cover member 3B is attached. By forming the second wall portion 414B in this manner, the cover fixing member 4B can increase the rigidity of the cover member 3B in the three-sided frame 1B.

[0058] The cover fixing member 4B and the three-sided frame 1B equipped with the cover fixing member 4B in the above-described embodiment can achieve the same effects as the cover fixing member 4 and the door 1 equipped with the cover fixing member 4 described above.

[0059] In addition, those skilled in the art can appropriately modify the switching device of the present invention in accordance with conventionally known knowledge. As long as such modifications still include the configuration of the present invention, they are of course included in the scope of the present invention.

[0060] For example, in the above-described embodiment, the object for which the cover fixing members 4, 4B are used has been described as fixing the cover members 3, 3B covering the recesses 22, 22B provided in the frame portions 2, 2B of the door 1 or three-sided jamb 1B to the frame portions 2, 2B, but the present invention is not limited to this and can be used to fix the recesses of various metal members to the cover members covering those recesses.

[0061] Furthermore, in the above-described embodiment, an example was described in which the recesses 22, 22B to which the cover fixing members 4, 4B are attached are provided in the side portions 21, 21B of the frame portions 2, 2B of the door 1 or the three-sided jamb 1B, but the position at which the recesses 22, 22B are provided is not limited to the side portions 21, 21B.
